Description

Technical Field

[0001] The present invention belongs to the technical field of electrical components, and in particular relates to a modular combined high-frequency switching transformer. Background Art

[0002] High-frequency switching transformers are widely used in fields such as smart grids, electric vehicles, and military aviation. As key components in power electronic transformers, they are used for voltage conversion, electrical isolation, power transmission and control, and bidirectional energy flow. Their design requires careful consideration of core materials, winding structure, insulation materials, and heat dissipation. For example, the transformer's core, insulation, and heat dissipation must be prioritized at high voltages and high frequencies. At high frequencies, non-sinusoidal waveforms often contain higher-order harmonics. These harmonics exacerbate the skin and proximity effects of the windings, increasing winding losses and making calculations more complex.

[0003] In the prior art, such as a new type of high-frequency switching transformer with application number: 202011363530.4, it includes: a magnetic core frame, a square hole for installing an E-type magnetic core is opened inside the magnetic core frame; a foot seat, the lower part of the magnetic core frame is symmetrically provided with foot seats, and the two foot seats are evenly spaced apart with winding grooves on the opposite sides; a connecting pin, the bottom of the foot seat is evenly spaced apart with connecting pins; an E-type magnetic core, the middle part of the two E-type magnetic cores can be detachably inserted into the square hole inside the magnetic core frame.

[0004] In the above, the combined splicing function of the switching transformer is basically realized through the combination of the magnetic core skeleton, the winding groove and the magnetic core. However, this transformer is an electrical component, and the winding and the adapter substrate are not clearly stated in the above technical solution whether the fit is tight, which may aggravate the skin effect of the winding, thereby increasing the resistance of the winding, which is extremely detrimental to the power-on function of the switching transformer; further, the limiting effect between the terminal pin and the winding groove is not obvious enough. When the exposed cable is powered on, some wires may be lifted and overlapped. This situation will lead to more serious short-circuit failure, and the switching transformer cannot be used stably for a long time. Summary of the Invention

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0035] Example 1

[0036] Reference Figure 1-3, which is the first embodiment of the present invention, provides a modular combined high-frequency switching transformer, including a bracket mechanism 100, the bracket mechanism 100 includes a side frame 101, and a magnetic core mechanism 200 is arranged on the side of the side frame 101. The magnetic core mechanism 200 includes an E-type magnetic core 201 that is snap-connected to the side of the side frame 101, and the inner side of the E-type magnetic core 201 is fitted with a winding group 302. The side of the winding group 302 is fitted with a straightening line 523 and a connecting block 515. The side of the straightening line 523 is snap-connected with a disk 520, and the disk 520 is adapted to be installed with a rotating shaft seat 522 on one side relative to the straightening line 523, and the outer surface of the disk 520 is fixedly connected to a support rod 521, and the surface of the support rod 521 is slidably connected to a slide block 519.

[0037] Specifically, the side frame 101 and the core mechanism 200 are arranged in a coordinated manner so that the core mechanism 200 can be stably placed, which facilitates assembly. The E-shaped core 201 and the winding group 302 are arranged in a coordinated manner so that the switching transformer has complete electrical functions. The card connection between the arranging line 523 and the disc 520 allows the winding group 302 to be combed and squeezed, which helps the winding group 302 not to bulge on the side when winding. After squeezing, the thickness of the winding group 302 is reduced and the width is increased, so that the cross-sectional area of the winding group 302 is reduced. The surface is changed into a strip shape, which further minimizes the skin effect of the winding group 302 when high-frequency power is applied, and the power-on function can be guaranteed to the greatest extent. The adaptive installation of the rotating shaft seat 522 and the disk 520 can make the rotation of the disk 520 more stable and efficient. The sliding connection between the support rod 521 and the slide block 519 allows the two to form a cam motion. The wire-squeezing effect of the winding group 302 by the wire-squeezing line 523 is continuously circulated, which is conducive to continuously reducing the influence of the skin effect on the electrical performance of the switching transformer.

[0038] Furthermore, the slide block 519 is an integrally formed rounded rectangular sheet metal frame, and a triangular gear seat 516 is adapted to be installed at the bottom of the slide block 519. The top rotating sleeve of the triangular gear seat 516 is provided with a locking shaft 517. The outer surface of the locking shaft 517 is fixedly connected to a right-angle seat 518. The upper surface of the right-angle seat 518 is fixedly connected to a square frame 501. There are several organizing lines 523, and the several organizing lines 523 are arranged equidistantly on the disc 520.

[0039] Preferably, the adaptive installation of the slide block 519 and the triangular base 516 allows the rotational motion of the triangular base 516 to be transmitted to the slide block 519, which facilitates cam transmission. The rotational sleeve of the locking shaft 517 and the triangular base 516 can ensure the stable rotation of the triangular base 516 and prevent the triangular base 516 from disengaging during rotation. The fixed connection between the square frame 501 and the right-angle seat 518 prevents the side of the triangular base 516 from being subjected to a large centrifugal force. The rotation frequency of the triangular base 516 on the horizontal plane remains constant, which is conducive to the stable transmission of motion. The equidistant arrangement of the plurality of sorting lines 523 makes the outer surface of the winding group 302 more efficient in being squeezed and combed, further reduces the resistance influence of the winding group 302, and makes the electric power of the switching transformer more efficient, which is conducive to better performance.

[0040] It should be noted that the continuous alignment mechanism 500 where the slide block 519 is located, the continuous alignment mechanism 500 also includes a first rack 512, the teeth of the first rack 512 are engaged with the triangular gear seat 516, and the end face of the first rack 512 is fixedly sleeved with an inner shaft 511, one end of the inner shaft 511 is fixedly connected to the second rack 514, the teeth of the second rack 514 are engaged with the transmission teeth 513, the transmission teeth 513 are fixedly connected to the square frame 501 through the side shaft seat, and one side of the transmission tooth 513 is clamped and connected with a connecting block 515, and the end face of the connecting block 515 is in close contact with the winding group 302.

[0041] Afterwards, the engagement of the first rack 512 with the triangular base 516 allows the triangular base 516 to swing continuously, indirectly improving the wire-squeezing efficiency of the wire-squeezing line 523. The fixed sleeve of the inner shaft 511 and the first rack 512 allows the first rack 512 to move horizontally, and the engagement efficiency with the triangular base 516 is better. The coordinated arrangement of the inner shaft 511, the second rack 514 and the transmission tooth 513 allows the connecting block 515 to squeeze and fiddle with the lateral side of the winding group 302, so that the external shape of the winding group 302 changes, thereby improving the low-resistance operation efficiency of the electrical component.

[0042] Example 2

[0043] Reference Figure 4-5 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides relevant parts to achieve a stable bonding effect between the winding group 302 and the substrate 301.

[0044] Specifically, the other end of the inner shaft 511 slides through the outer cylinder 504, the outer surface of the outer cylinder 504 is fixedly connected to the stabilizing seat 510, the stabilizing seat 510 is rotatably connected to the hinged shaft 509 through the inner pin shaft, the top of the hinged shaft 509 is fixedly connected to the ring 508, the inner side of the ring 508 is fixedly sleeved with the fixed shaft 507, and the outer surface of the fixed shaft 507 is adapted to be installed with the square frame 501.

[0045] Furthermore, the sliding penetration of the inner shaft 511 and the outer cylinder 504 makes the displacement of the first rack 512 more durable. The fixed connection between the stabilizing seat 510 and the outer cylinder 504 can stably move the outer cylinder 504 in the axial direction, reducing the shaking of the outer cylinder 504. The rotational coordination of the stabilizing seat 510, the hinged shaft 509 and the collar 508 significantly offsets the up and down shaking of the outer cylinder 504, indirectly ensuring the efficient engagement of the first rack 512. The fixed connection between the fixed shaft 507 and the collar 508 can provide fixed-point support for the rotational movement, and the rotation process is more continuous and stable.

[0046] Preferably, the inner cavity of the outer cylinder 504 is clamped with a straight spring 505, one end of the straight spring 505 is fixedly connected to the inner shaft 511, and the other end of the straight spring 505 is movably clamped with the push rod 502, the outer surface of the push rod 502 is plugged with an outer abutment plate 506, the end face of the outer abutment plate 506 is slidably connected to the through groove opened in the outer cylinder 504, and the end face of the push rod 502 is fixedly sleeved with a toggle rod 503.

[0047] Among them, the clip connection between the straight spring 505 and the outer cylinder 504 allows the straight spring 505 to be placed stably. The fixation of the straight spring 505 and the inner shaft 511 and the clip connection with the push rod 502 allow the push rod 502, which serves as the active component, to act on the inner shaft 511 through the elastic output of the straight spring 505, which is beneficial to the stable displacement of the inner shaft 511, and finally allows the connecting block 515 to continuously squeeze the winding group 302 and push the winding group 302 to be stably placed in the original position. The plug-in connection between the outer plate 506 and the push rod 502 can push the rod 502 and the outer cylinder 504 to a better degree of docking and sliding.

[0048] Afterwards, the winding mechanism 300 where the winding group 302 is located also includes a lead 303 and a substrate 301. The outer surface of the substrate 301 is snap-connected to the winding group 302. The lead 303 is cooperated with a wire management mechanism 400. The wire management mechanism 400 includes a straightening plate 401. The surface of the straightening plate 401 is fixed with a blocking ring 402.

[0049] In the above, the snap-fit connection between the substrate 301 and the winding group 302, and the lateral pushing action of the above-mentioned connecting block 515, make the winding group 302 fit better with the substrate 301, avoiding the problem of splicing failure. The coordinated setting of the straightening plate 401 and the blocking ring 402 makes the winding group 302 limited and straightened at the bottom, which is conducive to achieving safe and stable power-on operation.

[0050] Example 3

[0051] Reference Figure 6-7, which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides relevant parts to achieve the effect of placing the bottom of the winding group 302 in sequence.

[0052] Specifically, the bracket mechanism 100 also includes a base 102, a positioning shaft 403 is fixedly connected to one side of the base 102, a retaining ring 404 is rotatably provided on the surface of the positioning shaft 403, and the side of the retaining ring 404 is connected to a protruding tooth 405, and a limiting groove 406 is provided on the annular inner surface of the base 102, and the groove surface of the limiting groove 406 is movably engaged with the protruding tooth 405.

[0053] Furthermore, the fixed connection between the base 102 and the positioning shaft 403 allows the clamping ring 404 to stably tighten and organize the bottom of the winding group 302, preventing the exposed cables from curling up and affecting normal power supply. The clamping connection between the protruding teeth 405 and the limiting grooves 406 allows the tightening of the clamping ring 404 to be adjusted, meeting the organization needs of cables at the bottom of different numbers of winding groups 302.

[0054] Preferably, the snap ring 404 is an integrally formed semicircular silicone ring, and the snap ring 404 , the protruding teeth 405 and the limiting grooves 406 are arranged at equal distances on the surface of the base 102 .

[0055] The equidistant arrangement of the clamping ring 404, the protruding teeth 405 and the limiting grooves 406 significantly improves the efficiency of arranging the cables at the bottom of the winding assembly 302, and also speeds up the assembly and splicing of the switching transformer.

[0056] Example 4

[0057] Reference Figure 6-10 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides relevant parts for achieving stable support and E-type magnetic core alignment assembly effect.

[0058] Specifically, a distance is left between the support rod 521 and the installation position of the rotating shaft seat 522 , and the center of the rotating shaft seat 522 is kept coincident with the center of the disk 520 .

[0059] Furthermore, the support rod 521 is set at a distance from the rotating shaft seat 511, so that the slide block 519 realizes cam rotation. At the same time, the rotating shaft seat 522 is set to coincide with the center of the disk 520, further ensuring the stability and efficiency of the circular motion of the disk 520.

[0060] Preferably, there are two E-shaped magnetic cores 201 , and locking blocks 202 are adapted to be installed on opposite sides of the two E-shaped magnetic cores 201 , and the axes of the locking blocks 202 are kept on the same line.

[0061] The adaptive installation of the locking block 202 and the E-shaped magnetic core 201 enables the E-shaped magnetic core 201 to find the correct direction when docking, which is convenient and quick to assemble.

[0062] Working principle: First, a locking block 202 is set on the opposite side of the E-shaped magnetic core 201 to make the E-shaped magnetic core 201 aligned and plugged in. Then, the toggle rod 503 is pushed and pulled. The toggle rod 503 will drive the push rod 502 to move horizontally along its own axis. The displacement of the push rod 502 will compress the straight spring 505, allowing the inner shaft 511 to slide stably in the inner cavity of the outer cylinder 504. Then, the stable seat 510 fixed on the outer surface of the outer cylinder 504 and the hinged shaft 509 rotate to reduce the shaking caused by the sliding of the outer cylinder 504. The inner shaft 511 continues to move, which in turn drives the first rack 512 to move synchronously. The first rack 512 completes fixed-axis swing with the triangular gear holder 516 through tooth engagement. The triangular gear holder 516 slides with the support rod 521. Since the support rod 512 and the rotating shaft holder 522 have different center points, this sliding is converted into a regular swing of the bottom of the triangular gear holder 516, further allowing the straitening wire 523 set on the side to repeatedly squeeze and comb the winding group 302, helping the winding group 302 to be stably attached to the substrate 301.

[0063] In order to improve the problem of the winding group warping during the splicing process, the lead 303 at the bottom of the winding group 302 can be placed on the surface of the straight plate 401 and isolated with a blocking ring 402. At this time, the snap ring 404 is rotated to allow the protruding teeth 405 set on the side of the snap ring 404 to be tightened with the limiting groove 406 to organize and place the lead 303.
